It is a high-performance antioxidant, With its low volatility and thermal stability, Hydrolytic resistance is far better than similar antioxidants 626, Especially in some large water absorption materials and longer use cycle of the field to get better performance reflected; High in the melting point, High thermal decomposition temperature, During the high-temperature treatment process, Can protect the polymer from thermal degradation; It can substantially reduce the decolorization, Prevent an increased melt flow rate of the polymer, Provided a significant processing stability for the polymer, Therefore, it is suitable for applications that require high temperature treatment and avoid intense discoloration; It a good synergistic effect; Approved as indirect additives to food exposure substances in the United States, the European Union, and Japan, Allowed to be applied to food packaging.
It can be applied to: polyolefin, such as PP and HDPE styrene resins, such as PS and ABS, engineering plastics, such as PA, PC, m-ppe, polyester.
